Matcha slice cake from Biockas

Visited Biockas on a train strike day because only the over ground was running and got some delicious cakes.
On the way to the Overground, I visited Brockas and got a matcha cake even though I don't like matcha.
The icing was decent with a strong matcha grassiness but the cake itself was too dense and gritty but then it was vegan.
